Mo Brooks has emerged as one of Congress’s premier climate change deniers.

What did the Alabama Republican House member say to an environmentalist today during a congressional hearing on climate change?

Check it out, as reported by USA Today: “Every single year that we’re on Earth, you have huge tons of silt deposited by the Mississippi River, by the Amazon River, by the Nile, by every major river system — and for that matter, creek, all the way down to the smallest systems,” Brooks said. “And every time you have that soil or rock whatever it is that is deposited into the seas, that forces the sea levels to rise. Because now you’ve got less space in those oceans because the bottom is moving up.”

There’s a bit more: Brooks pointed to the White Cliffs of Dover and to California “where you have the waves crashing against the shorelines” and “you have the cliffs crash into the sea.”

“All of that displaces the water which forces it to rise, does it not?” Brooks asked.

That’s it. Rocks are filling the ocean bottom, forcing the water to rise — worldwide! That’s the Mo Brooks doctrine.

Carbon pollution? Deforestation? Other causes that might come from human activity? That’s a non-starter among climate change deniers, such as Rep. Brooks.

Such so-called “thinking” tells me that those who deny the link between the changing climate and human behavior have rocks in their heads.
